US Patent Issued to STMicroelectronics International on Nov. 3 for "Vibrational MEMS structure, in particular gyroscope, having spurious mode test structures, test system and method" (Italian Inventors)

ALEXANDRIA, Va., Nov. 3 -- United States Patent no. 12,782,130, issued on Nov. 3, was assigned to STMicroelectronics International N.V. (Geneva).

"Vibrational MEMS structure, in particular gyroscope, having spurious mode test structures, test system and method" was invented by Gabriele Gattere (Castronno, Italy) and Luca Guerinoni (Alzano Lombardo, Italy).

According to the abstract* released by the U.S. Patent & Trademark Office: "Test method of a vibrational MEMS structure wherein, a direct, variable modification voltage is applied to a resonance modification test structure having non-rectilinear electrodes, modifying the resonance frequency of the movable mass and the driving frequency. During the test, the movable mass is verified abou...
